Reaction Steps
To a solution of 2-amino-5-nitropyrimidine (3.00 g, 21.4 mmol), 4-dimethylaminopyridine (2.61 g, 21.4 mmol) and pyridine (10.4 ml, 128 mmol) in acetonitrile (100 ml) was added acetyl chloride (3.04 ml, 42.8 mmol), the mixture was stirred at 100° C. for 1 hour. To the mixture was added acetyl chloride (2.00 ml, 28.1 mmol) and the mixture was stirred at 100° C. for 12 hours. The reaction mixture was poured into ice-water and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was recrystallized from a mixed solvent of hexane and ethyl acetate to obtain the desired product (1.22 g, 31.3%) as a solid.
